Question

In order to determine the emf of a storage battery

Answer 1

let asuume E is the unknown potential

E+E2= V1+I1R

E= v2+I2R

 

taking differnce  

E2= v1-v2+ (I1-I2)R

This equation give R,  

putting back R gives E , the unkwon emf.

Answer 2

Answer:

let asuume E is the unknown potential

let asuume E is the unknown potentialE+E2= V1+I1R

let asuume E is the unknown potentialE+E2= V1+I1RE= v2+I2R

let asuume E is the unknown potentialE+E2= V1+I1RE= v2+I2R

let asuume E is the unknown potentialE+E2= V1+I1RE= v2+I2R taking differnce

let asuume E is the unknown potentialE+E2= V1+I1RE= v2+I2R taking differnce E2= v1-v2+ (I1-I2)R

let asuume E is the unknown potentialE+E2= V1+I1RE= v2+I2R taking differnce E2= v1-v2+ (I1-I2)RThis equation give R,

let asuume E is the unknown potentialE+E2= V1+I1RE= v2+I2R taking differnce E2= v1-v2+ (I1-I2)RThis equation give R, putting back R gives E , the unkwon emf.
